| Summary | This study aims to develop a land use design model for transit-oriented development (TOD) planning. The model is developed to distribute the residence, employment, and recreation activities in an urban area. The input and output of the developed model can be grey numbers, which can deal with the uncertainty and flexibility of real world effectively. The model was developed based on the following four objectives: maximizing the environment qualities of the city, maximizing the interaction convenience among activities, maximizing the subway’s ridership, and maximizing the accessibility of commercial and business areas as well as the following constraints: carrying capacity, differences to the present conditions, economical scale, characteristics of development, and capacity of subway system. A Grey TOPSIS approach is designed to solve the developed mode, and it can be applied by the other grey multiobjective programming. Finally, the model is applied on the TOD planning for Taipei City. Besides the development recommendation for case study, it is also found that the less indefinite information is in grey parameters of model, the higher grey degree outcomes have. It is useful to remain flexibility of planning for responding to the uncertainty and risk. |
